ROLLER FOR TYPE-WRITERS..

Specification of Letters Patent.

Patented Feb. c, 190e.

Application nea August 15, 1904. serai No. 220,850.

My invention relates to rollers or. platens for type-writers; and the objects of my invention are to provide a roller which shall render lthe operation of type-Writing Inachines more nearly noiseless .than heretofore, to make a more durable roller, and to reduce the wear on the type, especially when hard or hard-surfaced sheaths are em loyed to receive their impact.' I accomplish these objects by means of one or more soft-rubber* cushions inclosed within the outside sheath and which cannot harden, because they are entirely inclosed, covered, and protected.

An embodiment of my invention is shown in the accompanying drawings, in which- Figure 1 is a longitudinal section of my roller. Fig. 2 is a cross-section of the same, taken on the linea: :1; of Fig. 1.. i

The ysupporting structure of the roller is a` hollow tube 1, preferably of wood and having -at one end an inte ral enlarged head2, as shown in Fig. 1,. t the other end is a similar enlarged head 3, vwhich is detachable, preferably by means of screw-threads` such as shown, between the head 3 and the reduced end 4 `of the wooden tube. The wooden heads are shown as having recesses 5 6 to receive the metallic end plate and'also the ratchet-plate, which are ordinarily associated with lsuch rollers. In the space surrounding the wooden center and between the enlarged heads is a packing or cushion 47, which is made of soft rubber, preferably lRara rubber of good quality. This packing may be a hollow tube or cylinderof rubber separately manufactured and of a size to properly iit the s ace and lie flush with the heads, or it ma fie molded of rubber upon. and around tfie wooden tube in the same position. Then the exterior sheath 8, of hard, soft, or medium rubber, is placed in position so as to cover and inclose thecushlon and both'heads.

In addition to the cushion heretofore described I consider it desirable to employ a second and interior cushion 9 in order to insulate thewooden tube from the metal rod which passes through the center and forms the journals of the roller. I have therefore illustrated such an interior cushion, which is a soft-rubber tube which makes a` substantially close fit between the inner surface of the wood and the longitudinal. rod.

By the construction described the entire working surface of the sheath is underlaid by a soft elastic cushion which is not exposed,

and hence retains its soft elastic qualitiesduring long use. In addition the central cushion acts as an elastic backing for the wood, which ordinarily is in contact with the metal rod and forms an additional factor in the comparative noiselessness of machines equipped with -my rollers.

Rol ers or platens constructed according to my invention possess Vall the advantages of hard, soft, or medium surfaced latens, according to which of theseV kinds o sheath is used, and have their own special advantages in that noise is to a great extent overcome, while at the same time the durability of the platen is greatly increased, hardening of the surface in use is prevented, danger of injury to the t e reduced, and the life of `such type lengt ened.,l In obtaining-these advantages I in no way detract from the alinernent, clearness of 1mpression, or man1- fold'mg qualities possessed by various kinds' of type-writers equipped with ordinary rollers or platens.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is`` A roller for type-writers comprising a hollow woodenbody having an enlarged head L. W. SEELY, M. R. SEELY.
